Oregon quarterback Bo Nix exited late in the fourth quarter versus Washington on Saturday with an apparent lower-body injury.
Nix suffered the ailment after taking a hit on a third-and-5 red-zone run. He required assistance heading to the bench and was replaced by Ty Thompson on the next drive with the score tied at 34.
The Ducks starter returned for the team's final drive, but Oregon failed to score and lost 37-34.
Nix will have a week to heal before Oregon faces Utah on Nov. 19.
